Q76. During a design review, an engineer must reason about robot rather than rely on a memorized label. Which statement is defensible?

A. a manually operated hand tool B. a passive fixture with no controlled motion C. a device used only for measurement D. A programmable, multifunctional machine that performs tasks automatically

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: A robot combines mechanical structure, actuation, sensing and control so it can carry out programmed tasks. It is not merely a hand tool or passive fixture. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q77. Which option correctly identifies the function or significance of end effector in robotics? (select the best answer)

A. The device attached to the robot wrist that performs the task B. the main processor C. the base mounting plate only D. the encoder interface

Check Answer

Correct Answer: A   |   Marks: 1

Explanation: End effectors include grippers, welding guns, paint guns and tools. They interact directly with the part or process. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q78. A robotics student is asked to distinguish repeatability from unrelated system features. Which answer is correct? (select the best answer)

A. the difference between commanded and measured positions in every case B. The ability to return repeatedly to the same position under the same conditions C. the maximum working radius D. the number of axes

Check Answer

Correct Answer: B   |   Marks: 1

Explanation: Repeatability describes consistency across repeated approaches. Accuracy instead concerns closeness to the commanded or true position. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q79. Which statement would be the soundest basis for explaining DOF to a new robotics engineer? (select the best answer)

A. the number of grippers fitted B. the maximum payload in kilograms C. The number of independent coordinates needed to describe a robot's configuration D. the number of sensors only

Check Answer

Correct Answer: C   |   Marks: 1

Explanation: Degrees of freedom count independent motions or configuration variables. They do not directly state payload, gripper count or sensor count. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q80. In a technical review of a robot, which statement about automation should be accepted? (select the best answer)

A. requiring a person to guide every motion by hand B. removing all sensing from a process C. using only fixed hand tools D. Using control systems and machinery to perform tasks with reduced direct human intervention

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: Automation uses machines, controllers and often sensors to execute repeatable operations with less manual intervention. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q81. During a design review, an engineer must reason about work envelope rather than rely on a memorized label. Which statement is defensible?

A. The set of locations the robot's end effector can reach B. the controller's memory capacity C. the robot's rated payload D. the range of programming languages

Check Answer

Correct Answer: A   |   Marks: 1

Explanation: The work envelope is the reachable spatial region determined by geometry and joint limits. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q83. A robotics student is asked to distinguish controller from unrelated system features. Which answer is correct? (select the best answer)

A. the component that only grips the workpiece B. the structure that supports the robot C. The unit that processes commands and coordinates robot motion D. the power source alone

Check Answer

Correct Answer: C   |   Marks: 1

Explanation: The controller interprets programs and feedback and sends commands to drives. The manipulator provides structure, while the end effector interacts with the workpiece. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q84. Which statement would be the soundest basis for explaining manipulator to a new robotics engineer? (select the best answer)

A. the software program only B. the safety fence C. the external power cable D. The linked mechanical structure and joints that position the end effector

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: The manipulator is the robot's mechanical arm, links and joints. Programs, fences and cables are supporting elements, not the manipulator. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.
